Diet Soda & Diabetes 2023: Is Diet Soda Good For Diabetes?

As a person living with diabetes, paying close attention to what you consume is essential, especially when it involves sugar content. While diet sodas may seem healthier due to their low or zero-calorie content, you still need to consider the potential risks of artificial sweeteners.
Although diet sodas may serve a purpose as a short-term replacement for sugar, water is typically your ideal drink when managing diabetes. This article will help you make an informed choice about your beverage intake and how to manage your blood glucose levels if you consume soda or sugar-sweetened beverages daily.
Can Diabetics Drink Diet Soda?
More research is needed to fully understand the link between diet soda and diabetes. However, people with diabetes should be cautious about consuming diet sodas since they contain artificial sweeteners that can disrupt the body’s ability to regulate blood sugar levels and insulin response and trigger sugar cravings. Instead, healthier alternatives such as water, low-calorie flavored drinks, and teas and coffee without sweeteners are recommended.
Diet Soda And Diabetes
The risks associated with diet soda mean it cannot be a magic cure-all for people with diabetes.
Diet soft drinks or no-calorie sweetener soda has long been marketed as a healthier alternative to regular soda, especially for people with diabetes who must watch their sugar intake.
However, studies have shown that diet soft drinks may increase the risk of developing type 2 diabetes. This is because diet soda contains artificial sweeteners, such as aspartame and sucralose, which can disrupt the body’s ability to regulate blood sugar levels and insulin response.[1] In addition, the artificial sweeteners of diet soda can also trigger cravings for sugary foods — leading to overeating and weight gain, which are both risk factors for diabetes.
So, is diet soda bad for diabetes? More research is needed to fully understand the link between diet soda and diabetes. However, people with diabetes should be cautious about consuming these beverages. Instead, they might consider healthier alternatives such as water, unsweetened tea, or sparkling water with a splash of fruit juice. Small changes to one’s diet and lifestyle can significantly impact your diabetes management and overall health.
What Are Diet Sodas?

Diet sodas are a popular beverage choice for those looking to reduce their sugar and calorie intake. Unlike sugar-sweetened beverages that are typically loaded with sugars and high in calories [2] diet soda is sweetened with artificial sweetener. By choosing diet soda, you can enjoy a refreshing drink without the added sugars that can negatively affect your blood glucose levels and overall health.
One of the primary features of artificially sweetened beverages is that they are typically calorie and carbohydrate-free. This makes them an attractive option for those with diabetes or those who want to lower their calorie intake for weight management reasons. Artificial sweeteners, such as aspartame, sucralose, and saccharin, are often used in these beverages to mimic the taste of sugar while providing minimal or no calories.
When considering if artificially sweetened beverages suit you, it’s essential to understand the potential health risks, your unique dietary needs, and the importance of moderation in consumption. Remember to consult a registered dietitian or healthcare professional certified in diabetes education for personalized advice on managing your blood sugar levels.
Do Diet Sodas Raise Blood Sugar?
The answer to that question may surprise you. While diet sodas don’t directly impact your blood sugar[3] or A1C levels, you should still be cautious about other factors that may indirectly affect your blood sugar levels.
For example, researchers have found a significant link between diet soda consumption and the development of high blood sugar levels and belly fat,[4] two indicators of metabolic syndrome.[5]
Additionally, a 2022 study highlighted the adverse effects[6] of numerous sweeteners on the gut microbiome, adversely affecting glucose tolerance over time. The worst offender in this study was sucralose, although saccharin, aspartame, and stevia affected the gut microbiome to some degree.
Still, while aspartame may be found in carbonated beverages that contain carbohydrate calories, far less is needed to achieve the desired sweetness.
It is always important to be mindful of your overall diet and lifestyle choices to manage your diabetes effectively. Here are a few tips to help you make better choices regarding diet soda and blood sugar management:
- Opt for water, unsweetened tea, or black coffee when possible, as they will not impact your blood sugar levels.
- Limit your overall consumption of artificially sweetened products, as some individuals may not be able to manage blood glucose levels effectively in response to these sweeteners.
- Stay active and maintain a healthy weight to reduce the risk of developing conditions like metabolic syndrome.
Remember, you can make informed choices about your health and diet.
Risks Of Drinking Diet Soda
Although consuming diet soda may seem like a better alternative to sugary beverages for managing blood glucose levels, it comes with its own risks. One major concern is that diet soda consumption correlates with an increased risk of cardiovascular disease,[7] although there is no evidence that it increases[8] blood pressure. These conditions can be particularly concerning for people with diabetes, who are already at a higher risk for heart problems.[9]
Diet soda consumption may also be linked to gain weight rather than loss. Even though the drinks are low in calories, research has shown they can stimulate your appetite.[10] This can lead to overeating and, ultimately, weight gain. This can be particularly problematic for people with diabetes, as maintaining a healthy weight or healthy diet is essential for managing the condition.
Alternative Diet Drinks For Diabetes

As someone who struggles with sugar cravings and managing blood glucose levels, you may be searching for healthier alternatives to diet soda or drinks made with natural sweeteners. Thankfully, there are several options to choose from. Here are a few suggestions that taste great and provide essential nutrients to support your health.
Water Infused With Fruits Or Herbs
Staying hydrated is crucial for everyone, especially those living with diabetes. Infusing water with fruits or herbs adds flavor and enjoyment and has minimal impact on your blood sugar levels. Feel free to get creative by mixing different ingredients, such as lemon, cucumber, strawberry, or mint. The result is a refreshing, low-calorie drink or fruit juice can keep you hydrated throughout the day.
Unsweetened Iced Tea
Unsweetened iced tea is a refreshing beverage. Opt for herbal teas or green tea, which contain antioxidants that may benefit your overall health. Remember to avoid adding any sugars. If needed, you can lightly sweeten your iced tea with a natural, low-calorie sweetener like monk fruit.
Vegetable Juice
Vegetable juice is a nutrient-dense alternative to diet soda. Tomatoes, carrots, and leafy greens can be excellent choices for juicing. Just be mindful of portion sizes and remember to consume vegetable juice without any added sugars.
Low-fat Milk Or Unsweetened Almond Milk
Low-fat milk or unsweetened fortified almond milk can be a nutritious alternative to diet soda. Plus, it can provide essential nutrients[11] such as calcium, protein, and vitamin D. Still, keep an eye on portion sizes, as milk does contain some natural sugars.
Choosing alternative drinks or supplements low in carbohydrates and sugars can help you manage your diabetes effectively. Enjoy exploring these refreshing alternatives to diet soda and quench your thirst for a healthier lifestyle.
The Bottom Line
The impact of foods and beverages on blood sugar levels is vital to consider when managing diabetes. Although the evidence may be contradictory, research points to a connection between diet soda and blood sugar levels. If it contains artificial sweeteners, it might not be the best for blood sugar control as these have been linked to a higher risk of type 2 diabetes, body weight gain, and metabolic syndrome.
Both regular and diet soda intakes have also been linked to increased risks of diabetes and metabolic syndrome. Therefore, it is recommended to opt for healthier alternatives such as water, low-calorie flavored drinks, and teas and coffee without sweeteners. Overall, prioritizing healthier beverage options can help you better manage your diabetes and overall health.
